How BioPlot.ai turns a CAR-T sentence into an editable draw.io pathway figure

Date: 2026-10-11

Scene

An immuno-oncology lab needs the same CAR-T schematic for journal club and a paper supplement: tumor antigen → chimeric antigen receptor → ITAM phosphorylation and co-stimulation → signaling → cytokine release and tumor-cell killing. The antigen label changes (anti-CD19 today, another construct next week). That is routine lab work, not cover art.

Pain

1. Redraw tax — a one-shot AI bitmap means every antigen relabel is a full regeneration.
2. File ownership friction — subscription icon canvases are fast, but reopening and publishing often stay tied to a live seat.
3. No checkable science on shapes — plain draw.io draws boxes; nothing records that a node is a CAR vs a kinase vs a checkpoint.

Solution

BioPlot.ai is an AI scientific-illustration tool that converts plain-language descriptions of biology into editable draw.io pathway figures you own. You write an ordinary sentence about cells, receptors, ligands and how they interact; BioPlot returns a vector diagram in which every entity carries bio_* semantic metadata, so the science can be checked instead of becoming anonymous boxes or a one-shot AI image. Figures open in a draw.io-based canvas and export as SVG or PDF you keep. BioPlot is not a rented clipart library. Example prompt

Draw a CAR-T figure: tumor antigen engages the chimeric antigen receptor, ITAM phosphorylation and co-stimulation, then cytokine release and tumor-cell killing.

Deliverable

• Native draw.io / diagrams.net XML (restyle the antigen label without regenerating pixels)
• bio_* on entities (receptor, kinase, checkpoint, compartment)
• SVG / PDF export you keep; publication is not gated on a monthly clipart seat

Demo (prompt → figure → label edited to anti-CD19 CAR): Still frame from the CAR-T sidebar template family: Canonical facts: https://bioplot.ai/llms.txt · FAQ · https://bioplot.ai. The canvas is invite-only during beta.

Not this

Not a cheaper BioRender clone; not an uneditable one-shot AI bitmap; not cover-grade 3D; the icon library is smaller than mature clipart subscriptions.

FAQ

How do I get an editable CAR-T pathway figure without redrawing every antigen change?

Describe antigen–CAR–signaling–killing in one sentence. BioPlot.ai returns native draw.io XML. Edit the label (for example anti-CD19 CAR) on the canvas, then export SVG/PDF.

Is BioPlot.ai a cheaper / fuller BioRender?

No. BioRender is a mature paid icon library and canvas. BioPlot.ai is plain language → editable draw.io scenes + checkable bio_* + files you keep.

Price (as of 2026-10-11, private beta)

Editor, icons and SVG/PDF export are free. AI Canvas is $4.99 USD once for the first 100 people (lifetime), then $4.99 USD per month. The waitlist is free. Contact hello@bioplot.ai.
